Install:
   1. Patch the FreeBSD kernel:

   cd /usr/src;
   patch -p0 < uipc_socket.c.patch
   patch -p0 < ip_input.c.patch
   patch -p0 < socketvar.h.patch
   patch -p0 < sys_conf_options.patch
   patch -p0 < sys_i386_conf_GENERIC.patch
   2. Rebuilding FreeBSD kernel:
   cd /usr/src/sys/arch/i386/conf;
   config GENERIC;
   cd ../compile/GENERIC;
   make depend;
   make;
   make install;
   3. Compile ipvs module:
   cd ipvs/
   make;
   cd ipvsadm/
   make install;
   4. Compile ipvs scheduler module:
   cd ipvs/
   cd schedulers/
    cd SCHEDULER-NAME/
   make
   5. Reboot with new kernel:
  reboot;

Let's assume your cluster has the following configuration:
Workstation with address:192.168.1.23 runs as dispatcher(FE:front end),
Workstations with address:192.168.1.33 and 192.168.1.38 run as real server(BE:back end).
Thay all share address:192.168.1.36,which is saw by client.

Start:

Assume using 'rr' schedule algorithm(optional: dh, lblc, lblcr, lc, nq, rr,
sed, sh, wlc, wrr).

LVS/DR:
   1. kldload ./ipvs.ko
   2. kldload schedulers/rr/ip_vs_rr.ko
   3. ./ipvsadm -A -t 192.168.1.36:80 -s rr
   4. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.33:80 -g
   5. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.38:80 -g

LVS/TUN:
   1. kldload ./ipvs.ko
   2. kldload schedulers/rr/ip_vs_rr.ko
   3. ./ipvsadm -A -t 192.168.1.36:80 -s rr
   4. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.33:80 -i
   5. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.38:80 -i

Stop:
   1. ./ipvsadm -C
   2. kldunload ip_vs_rr
   3. kldunload ipvs

Note:Do not use other commands of ipvsadm,for maybe it is not implemented.
